If it is not a "guaranteed stop" then your trigger price will still gap down to the next traded price. I just had a quick look at the site and it looks as though they don't offer a guaranteed stop.

You need to dig deeper, You need to find out if they are a DMA (direct market access) or MM (market maker).
If they are DMA your stop will be triggered at the next traded price. MM can choose to take your order on or execute it on the live market. In any case, without a guaranteed stop feature your capital could be in trouble.


Here is a screen dump from Saxo

So as you can see, the stop is executed when the price is traded. So if it gaps through your stop price you will be stopped out at the next traded price under your stop.
The only way out is to cop the margin and cancel your stop and hope the price comes back...(Not a good Option IMO)

At a glance, I have to agree with systematic. Move your funds and speak to someone with a solid knowledge of the law.
Find out if your dealing with a DMA or a MM. This could vary your options.
Find out exactly your leverage, you need to know how many shares you are controlling.
Move your trading capital to a provider that has guaranteed stop as an option for your trade management.
